Question

Following are some events of mitotic cell division, select the correct order in which these events occur.
(i) Condensation of chromosomes is completed
(ii) Chromosomes lose their identity as discrete elements
(iii) Sister chromatids separate
(iv) Initiation of the assembly of the mitotic spindle

• A. (i) - (ii) - (iii) - (iv)
• B. (iv) - (i) - (iii) - (ii)
• C. (ii) - (i) - (iv) - (iii)
• D. (iv) - (iii) - (i) - (ii)

Answer 1

Answer: (B)

Initiation of the assembly of mitotic spindle occurs during prophase. The condensation of the chromosome is completed during metaphase. Sister chromatids separate due to splitting of centromere during anaphase. Daughter reaches opposite poles and undergoes decondensation as a result hromosome lost their identity as discrete elements during telophase.
